The supersonic aircraft Concorde has a length of 63.0 meters when sitting on the ground on a typical day when the temperature is 18.0 Celsius. The Concorde is primarily made of aluminum. In flight at twice the speed of sound, friction with the air warms the Concorde's skin and causes the aircraft to lengthen by 21.0 cm.
